there is no way to express a number in hexadecimal format directly. This has not changed between at least 8.1.7 and 11.1. Search the SQL Language Reference provided on tahiti.oracle.com for "Literals".
Of course there is no need to convert the table data to hexadecimal, but you do have to convert the hexadecimal representation '1F' to the type in your table.
